Uses: Mainly used for the intensity of a series of slightly higher than the intensity of work, pressure tanks, storage tanks, insulation materials, mechanical parts, fuel tanks and other aircraft. Conventional applications in air conditioners, refrigerators, car bottom and other humid environment, the price is higher than the 1 × × × series, is a more commonly used alloy series.

3003 is used to process parts that require good formability, high corrosion resistance, good solderability, or require both these properties and work harder than 1XXX alloys. Various pressure vessels and pipes

3004 aluminum cans can body, requiring more strength than the 3003 alloy parts
